GAS-BURNER.

Specicaton of Letters Patent.

Application tiled February 91 1906. Serial Nm 300.351.

Patented Dec. 17, 1907.

To all whom it may concern.'

Be it known that I, AUGUST MEYER, a citi- Zen of the United States,residing at Baltimore city, in the State of Maryland, have inventedcertain new and useful Improvements in Gas-Burners, of which thefollowing is a specification,

This invention relates to improvements in gas burners, and moreparticularly to a burner especially adapted to be operated by aclockwork or time mechanism, the burner being particularly intended foruse upon street lamps.

While the burner about to be described may of course be operated byhand, yet as before stated, it is especially designed to be operated bya time mechanism, and particular attention has been paid to theconstruction of the burner with a view of providing a valve and otheroperating parts that will require a minimum amount of power to operateit, or such power as can be practically derived from a clockwork or timemechanism of simple construction.

The burner belongs to that class of burners in which a by-burner orpilot lighter is employed to maintain a small flame for the purpose ofigniting the main volume of gas as it issues i'rom the main passage ofthe burner.

The main obj ect of this invention is to provide a burner, the valve andother operating parts of which will be of simple construction andrequire a minimum amount of power and degree of movement of parts forits el"- iicient operation, the parts being so constructed that frictionand liability to stick, as a result of gas deposits or other causes, arepractically eliminated.

In my application ,filed November 4, 1905 Serial No. 285,891, I fullyillustrated and described a novel clockwork mechanism in connection witha burner of construction different from the burner about to bedescribed, which mechanism may be equally well adapted to operate thisburner.

In Figure 1, of the drawings forming a part of this application, aclockwork or time mechanism is shown in connection with the burner,which mechanism corresponds to that illustrated in detail in myapplication referred to. However those parts of both burners whichdirectly cooperate with the elements of the time mechanism are the same,that is to say this burner, as well as the burner of my formerapplication, is proat pre-determined intervals by devices actuatedthrough the clockwork or time mechanism to accomplish the operation ofthe valves to light and extinguish the lamp.

In the drawings illustrating the invention: Fig. 1 is a front elevationof the burner, showing in connection therewith in front elevation, aclockwork or time mechanism, or such of the parts thereof as isnecessary to show the connection between said mechanism and that part ofthe burner operated upon or actuated by the mechanism, to light andextinguish the lamp. Fig. 2, is a longitudinal central section throughthe burner body, showing the main and pilot gas passages, and the portsor openings through which communication is established vided with a rockshaft adapted to be rocked between the gas chamber and said passages. A

Fig. 3, is a transverse section taken on about line .fr-, of Fig. 1.Fig. 4 is a section taken about on line y-fy of Fig. 3 showin thenvalves in elevation, one position o the valves being shown in dottedlines. Fig. 5, is a side elevation and plan of one of the valves. Fig.6, is a top plan view of one of the conduits which form valve seats forthe valves, and through which the gas passes, which gas is supplied froma suitable source to the main and pilot7 passages in the burner. Fig. 7,is a side elevation of the rock shaft to which the valves are attached,and Fig. 8, is a front' elevation of the burner showing a slightmodification adapting it to be operated by hand, either when the burneris used in connection with the time mechanism, or alone.

Referring to the drawings: The numeral 1 indicates the burner body whichhas two passages therethrough, 3 and 4; the passage 3 being for thepassage of the main volume of gas, or that which is intended for thelighting volume; and that designated by 4 being for the gas supplyingthe pilot77 Each passage is closed at its bottom by screw plugs formingparts of needle valves 5, by which the flow of gas and its pressure maybe regulated.

The numerals 6 and 6 are ports opening into the burner passages, theport 6 being for the admission of the main or lighting volume of the gasand 6 for the gas 'supplying the pilot. Fitted into these ports areconduits 7 and 7 which extend a short distance into a gas chamber 8,formed at the rear side of the burner. Each conduit has a passagetherethrough as shown, for the obvious purpose of permitting the gas atproper times to pass from the chamber 8 to one or the other of theburner passages; The conduits are tapered at the ends within thechamber, as indicated at 9, and form valve seats for two disk valves 1()and 10. ates in connection with and controls the supply of gas to themain burner passage, while the valve 10 operates similarly with relationto the conduit 7. The valves are preferably in the form of thin disks,and each is provided with an eye 11 by means of which they are looselyconnected to a thin segmental plate 11/, which in turn is rigidlyconnected to a rock shaft 12, which passes 4,through and has a bearingin an opening 13 in the body. To the front end of the rock shaft arocker arm 14 is rigidly attached. This arm is provided with two shortpins 15 .and 15', for a purpose which will presently become apparent.interposed between the rocker arm 14 and the front surface of thecasting is a thin leaf spring 16, which exerts a tendency to keep theslightly tapered or beveled portion 17 of the rock-shaft snugly againsta corresponding seat in the rear wall of the burner body.

The numeral 18, designates a light spring having its lower end attachedto a pin 19 in the chamber 8, andits upper end looped over a short pin20 carried by the segmental arm 11. This spring is for the purpose ofholding the valves properly seated upon their seats, and acts inaddition to the gas pressure which would also have a tendency to seatthe valves. The spring is so are ranged that when the rock-shaft isrocked until the pin 20 passes the center of the shaft, said spring willinstantly seat the valve intended to be closed, and hold it properlyseated until the reverse operation takes place.

Connected to the lower part of the burner body, and which may' form apart thereof, is a gas connection 21, internally threaded for thereception of a gas-pipe 22, which in the arrangement herein shown, andmore par ticularly in dotted lines Fig. 1, passes around the clockworkor time mechanism casing 23, and is led into another gas connection 24,by which last connection the whole device is adapted to be attached tothe gas-pipe sup plying the gas to the street or other lamp.

In Fig. 1, the burner is shown provided with a bracket 25 by which, andby means of screws 26 it is attached to the upper side of the casing 23.The numeral 27, designates two rods which are suitably guided in abracket 28 on the front of the burner` body. These rods are identical inconstruction and function with those shown in my applicationhereinbefore referred to, and they are actuated by the clockwork or timemechanism at The valve 1() operpre-determined intervals or times. Theserods move vertically and the movement of one or the other brings it intoengagement with one or the other of the pins 15 or 15 on the rocker arm14, for the obvious purpose of causing the valve, through the medium ofthe rock shaft 12, to be operated to establish communication between oneor the other of the burner passages and the chamber 8, as the exigenciesof the case may require.

It is highly desirable in burners of this character that the pilotlighter be extinguished when the lighting volume of the gas is turnedon, and that it remain extinguished while the lamp is lighted, as thus aconsider- `able amount of gas is saved where a great number of burnersare involved asin the case where a city is lighted. It is important toothat the burner and its parts be so arranged that the pilot" will beinvariably lighted from the dying flame of the mainburner as it is beingextinguished. When this burner is used in connection with the timemechanism, for which it is more particularly designed, the movement ofthe rock-shaft and valves can be regulated to the greatest nicety,closing one of the valves and opening the other, quite slowly or in factwith any degree of rapidity that the efficient operation of the devicemay require. With a comparatively slight movement of the rock-shaft andvalves, consuming probably five seconds, the liame of either the main orpilot burner will be caused to die slowly, giving either the one or theother as the case may require, ample time to light.

In my application No. 285891, I describe and illustrate a means foraccomplishing a slow movement of the rods 27 when the hour is reached atwhich the lamp is to be lighted or extinguished. In that application themovement of the rods at pre-determined times is accomplished by means ofor with the aid of cams, and it merely becomes a question of shaping theoperative cam surface to produce the desired movement of the rods.

As before stated the casing 23 contains a clockwork or time mechanismhaving suitable dials and indicators thereon denoting the time when thelamp is to be lighted and extinguished and to denote the time of theday. These features are all fully described in my applicationhereinbefore referred to and need no further description here.

In operation, with the parts as shown in full lines in the drawing,communication between the chamber 8 and the pilot passage is nestablished, inV which the pilot lighter will be burning, while the mainburner passage is closed. When the rock shaft is rocked toward the pilotlighter, the valve 10 will be lifted from its seat, establishingcommunication between the chamber 8 and the main burner passage, whilethe valve 10 Will be seated upon its seat cutting off communicationbetween said chamber and the pilot passage, and the spring 18 which hasbeen slightly tensioned, or rather has had its tension slightlyincreased by the movement of the shaft, will when it has passed thecenter of the shaft, exert a sudd en downward pull upon the segmentalplate ll', and thus cause the valve 10 to be properly seated.
